This is the Create MySQL HeatWave dialog's Configuration tab. The substeps following the image have information about each field. The fields System model (shape) and Data storage size (GB) are required, and MySQL version is optional. If you check the box Enable HeatWave cluster, the fields Node count and HeatWave shape are also required. Use the button at the end of the page to get to the next tab, which is Networking. Use the Review + create button when you have filled all the required fields on all the tabs - the dialog will tell you if you missed any.
